ARM32 issues only:

I haven't built egcs from a netbsd sup, but I have been using snapshots of 
the Cygnus egcs development.

The -msoft-float default should now be fixed in the Cygnus egcs-1.1 branch.

The compiler cannot compile libc's softfloat.c in the way that it was 
written (it exploited a bug in gcc 2.7 to return a structure that was 
larger than 32 bits in a register) -- I'm working on a fix for this, but 
haven't completed it yet.

I haven't decided yet whether the following is a bug in the linker, the 
compiler, somewhere in my installation or if I'm missing an arm-specific 
patch:  the linker I built from -current cannot generate correct shared 
libraries if they contain references to static data.  Eg:

static int foo;

int bar (int x)
  foo = x;

Which incorrectly calculates the address of foo.  I've established that 
the code generated by the compiler for the above is semantically the same 
as that generated by the old compiler, but I haven't got further than that 

No success yet building C++ programs, but that's probably because of the 
shared lib problem.
